Hi,

I have made a wechat payment plug-in based on official demo document, it includes 2 payment type, JSAPI and NATIVE.

The payment type, JSAPI, that can only be used inner wechat app.
And the type of Native (Scan a QR with wehcat app) can be used when a customer complete payment on PC.

You can test the demo of payment if you have installed wechat app on your mobile phone. paysdk.weixin.qq.com
For JSAPI payment, you must open the link on wechat app with the MicroMessenger browser.

Now, it still have some issues when I tested it.

Native payment can be done successfully, but callback notification can not run correctly.

JSAPI payment can not run correctly, it can only obtain a redirect code, can not obtain the user's openID and submit the order data to WeChat server for unified order operation (see admin.wechat.com/wiki/index.php?title=User_Profile_via_Web ).

OpenID is only needed for JSAPI payment but not for Native payment.

Callback notification process is the same for them.

When I test on PC with the NATIVE payment, I will not see a QR code to complete payment.
Because the function of GetPayUrl can't get parameter value of AppID and Key, unless use hard code in lib files.

I think that if wechat pay functions are written into the same class (plgHikashoppaymentWechatpay), it may be simple and running correctly.

But, maybe it's better to use the official demo libs.

So, can anyone give me some ideas?

I hope it's helpful to develop this plugin and add a new payment method for Hikashop, which is the best E-Commerce component with Joomla.

Here is the wechat official website (EN) pay.weixin.qq.com/wechatpay_guide/help_docs.shtml

Hello,

From what we know hard to tell you what is lacking, in order to process your test don't forget to use the log .
The idea is to process step by step in order to see sent elements and received from Payment servers.
In your plugin this kind of code will sent in the log :

$this->writeToLog("1° elements sent to Payment server :\r\n\r\n" . print_r($myElements,true) . "\r\n Recieved elements from payment servers :\r\n". print_r($ElementsPayment,true));

The other point is do you have contact with Wechat Payment support ? Or maybe you have in your merchant account a dashboard where you can see communication between your website and payment servers ?...

And finally, when we develop new payment plugin, we use most often the provided official libs from payment support, after having obviously a little adapted.
Hope this will help you.

Regards
